Title: Laser diode driving circuit
Inventor: KAMISAKA KATSUMI
IPC: H04B10/07
Filed: 1990-01-19
Abstract: PURPOSE:To compensate the fluctuation of an extinct ratio of a laser diode by using a current source circuit employing a diode having a same temperature characteristic as that of the laser diode and varying a signal amplitude current with the current source circuit. CONSTITUTION:A bias voltage depending on a forward voltage of a diode D and a constant current i1 generated by a constant current source 1 is applied to the base of a transistor(TR) Q3. The forward voltage is decreased in the diode D as the temperature rises. Thus, the voltage applied to the base of the TR Q3 is boosted to increase a modulation current i2 applied to the laser diode LD. As soon as a differentiation efficiency of the laser diode LD is changed, the voltage drop of the diode D is decreased, the voltage applied to the base of the TR Q3 is boosted and the modulation current i2 applied to the laser diode LD is increased. Thus, the signal amplitude of an outputted optical signal is unchanged regardless of the fluctuation in the differentiation efficiency of the laser diode LD.

IPC: F02F1/16
Filed: 1981-01-28
Abstract: PURPOSE:To improve adherence of casting by plating coil-shape linear made of metal wire wound compactly with metal having a melting point corresponding to or lower than of a cylinder block material, boring it after casting of cylinder block parent metal is done. CONSTITUTION:Coil-shape liner 1 made of metal wire wound compactly is plated with metal having a melting point corresponding to or lower than that of the melting point of a cylinder block material 3. Then the coil-shape liner 1 is casted with the cylinder block parent metal 3 so that the casted side of the coil- shape liner 1 is melted due to casting heat, and the casted side is melted with the cylinder block parent metal 3 to form alloy layer 2A. Consequently, the complete adherence condition is obtained between the liner 1 and the cylinder block parent metal 3. Then abrasion finishing is applied to the circumferential inner face of the liner 1. It is preferable to impregnate self-lubrication material between the metal wires before and during the finishing.

Title: Front lid attaching structure of timepiece
Inventor: TSUKAMOTO WATARU
IPC: G04B37/20
Filed: 1992-01-24
Abstract: PURPOSE:To enhance the opening and closing state of a front lid by utilizing the elastic force in the diameter direction of a C-shape fixing pin having a C-shape cross section as a clamping flap by using the C-shape fixing pin in the hinge engaging a portable clock case with a long lid. CONSTITUTION:A portable clock case 1 and an opening and closing type front lid 2 are connected by a hinge part 4 by inserting a C-shape fixing pin 3 in a hinge hole part 5. When a portable clock is usually carried in a state performing no clocking, the opening and closing type front lid 2 is in a closed state with respect to a portable case 1 but, at the time of clocking, the lid 2 is opened centering around the hinge part 4 with respect to the case. Since the diameter of the C-shape fixing pin 3 is set so as to be larger than that of the hinge hole part 5 permitting the insertion of the pin 3, the pin 3 is elastically pressed to the hinge hole part 5 by the elastic force ready to restore in the diameter direction of the pin 3 to be fixed thereto. The opening and closing force of the case 1 and the front lid 2, that is, the opening and closing state of the front lid 2 is affected by this elastic force but, since the elastic force is hard to receive the irregularity of the processing dimension of the pin 3, constant elastic force is obtained and the opening and closing state of the front lid is enhanced.
